This is the recommended path for anyone who knows they won't use their spa during the colder months. The goal is to get your spa perfectly clean and, most importantly, perfectly dry to prevent mould, mildew, or freeze damage during storage.
Step 1: Flush the Internal Pipes
Before you drain, you must clean the pipes you can't see. Remove your filters, add a dedicated hot tub pipe cleaner to the old water, and run the jets on full for 15-30 minutes as per the product instructions. This removes the hidden grime and biofilm.
Step 2: Power Down, Drain, Clean Bubble Chambers
Safety first. Switch off the power to your hot tub at the circuit breaker. Once off, drain the water using the built-in drain valve or a submersible pump for a faster result. Use a wet/dry vacuum to get every last puddle from the seats and footwell. Once Drained, switch the hot tub back on and run the bubbles for 2 minutes, it cleans out the air pockets on the bubble chambers
Step 3: Clean the Shell and Cover
Once empty, use a soft cloth and a proper hot tub surface cleaner to wipe down the entire shell, including the base underneath. Pay extra attention to the waterline, where oils gather. Clean your hot tub cover with a vinyl-safe cleaner, rinse it, and let it dry. NEVER USE A JETWASH!
Step 4: The Most Important Step: DRY EVERYTHING
This is the single most critical step for winter storage. Any moisture left behind will turn into mould and mildew in storage or freeze and crack components.
- Shell: Thoroughly dry the entire shell with soft, clean towels.
- Pipes: Use a wet/dry vacuum on the "blow" setting to force air and water out of the jet holes and plumbing lines.
- Pump/Heater: Disconnect the pump unit. Ensure it is fully drained and dry inside.
- Dry it some more: Give it an extra dry just to be sure!
Step 5: Pack and Store
When packing away always keep the cables outside of the hot tub. Ensure Filters are removed and carefully fold your spa and ensure it is kept away from any sharp objects and store all components in a safe, dry location that is protected from frost and rodents, like a garage or shed. Storing it in its original box is ideal. When you do come to unbox it next year let it warm up inside or in the sun before using it. You should also store all chemicals and accessories somewhere clean and dry and out of reach of children.
Inflatable Folding Technique

- Ensure the Wave Inflatable Hot Tub is turned off at the mains.
- Unscrew and remove the deflation valve.
- Push down on the Hot Tub side walls to help deflate.
- Once the Hot Tub is completely flat, fold the outer under the heater to push out more air from the system.
- Fold the two sections over each other and push out the remaining air.
- Store the lead and plug under the Hot Tub and place the unit in to its bag.
